%X We show how to \concatenate" variational principles over different bases into one over a single base, thereby providing a unifed Lagrangian treatment of interacting systems. As an example we study a Klein Gordon feld interacting with a mesically charged particle. We employour method to give a novel group-theoretic derivation of the kinetic stress-energy-momentum tensor density corresponding to the particle.
